158 CHIROPTERA and B. hipposideros ; antitragal lobe about half as high as conch, its width about equal to its height. Wing peculiar in the shortening of the first phalanx of fourth finger to a little more than one-third that of second (average of 10 specimens from Gard, France: first phalanx, 6-6 mm.; second phalanx, 17-4 mm.; ratio of first to second, 38 4-). Foot averaging slightly more than half as long as tibia. Colour.—While essentially as in Bhinolophus ferrum-equinum and B. hipposideros, the colour usually differs slightly in the more evident contrast of the light area between ears and the more drabby general effect of underparts. Median region below occasionally rather paler than usual, sometimes nearly as in B. mehelyi. Sktdl.—In both size (greatest length about 19 mm.) and form the skull is somewhat intermediate between that of Bhinolophus ferrum-equinum and B. hipposideros. It resembles or surpasses the latter in the breadth of brain-case relatively to narrow maxillary region, but more nearly agrees with the former in the nearly parallel-sided mesopterygoid space, the anterior border of which is separated from posterior molars by well defined palatal emarginations. The mesopterygoid space is, however, shorter in proportion to its width than in B. ferrum-equinum. Floor of brain-case between cochleas less narrowed than in the preceding species. Nasal region slightly less inflated than in B. hipposideros, and inflated area relatively shorter, its posterior border rising abrupth' above interorbital level. Teeth.—In all respects the teeth closely resemble those of Bhinolophus ferrum-equinum (apart from their smaller size), except that the upper canine is relatively less robust, the anterior upper premolar is less reduced (its crown area about double that of upper incisor), and anterior lower premolar is less crowded between canine and posterior premolar. Measurements.—For cranial and external measurements see Tables, pp. 156 and 160. Specimens examined.—About 130, from the following localities :— PoETUGAL: Cintra, 6, Spain: ViUalba, Lugo, 1; Madrid, 2; Silos, Burgos, 1, Fkance : St. Paterne, Indre-et-Loire, 3 (B.M. aud U.S.N.M.); St. Genies, Gard, about 50 (Mottaz); Gapeau Eiver, Var, 12. Italy: Near Genoa, 33 (B.M., U.S.N.M., Genoa, and Mottaz); Monte Pisanino, 2; Siena, 3 (U.S.N.M.); Eome, 2; VeUetri, Eome, 5 (U.S.N.M.); Niootera, Calabria, 1; Marsala, Sicily, 2, Sabdinia: Mount Gennargentu, 3 (U,S,N,M.). AcsTEiA-HuNGABY: Ofener Mountains, 2; Orsova, 1. Dalmatia : Zara, 1. Gbeece : Missolungi, Acarnania, 2 (U,S,N.M.), Bemarks.—Bhinolophus euryale is so readily distinguishable from all the other European members of the genus, except B. mehelyi, as to require no special comparisons. From B. mehelyi it is most easily distinguished by the form of the lancet and
